NASA powers discovery that enables us to learn more about ourselves, our world, and how to manage and protect it.

Features

NASA Renames Observatory For Fermi, Reveals Entire Gamma-Ray Sky
NASA's newest observatory, the Gamma-Ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays. GLAST has been renamed the Fermi Gamma-ray Space Telescope. The new name honors Prof. Enrico Fermi (1901 - 1954), a pioneer in high-energy physics.

Climate Time Machine
Look at changes in global ice melt, sea level, CO2 emissions, and average temperature conditions over time.

NLSI Lunar Science Conference
Conference sessions are structured to report on recent results and anticipate future opportunities for lunar science. Presentations on elements of education and public outreach are included to better understand how lunar exploration can be used to stimulate public interest in space exploration and improve science literacy.July 20, 2008 - July 23, 2008

OSTM
A new NASA-French space agency oceanography satellite launched June 20th from Vandenberg Air Force Base, Calif., on a globe-circling voyage to continue charting sea level, a vital indicator of global climate change.

Phoenix Lander Arrives on Mars
Phoenix will dig to an ice-rich layer expected to lie within arm's reach of the surface. It will analyze the water and soil for evidence about climate cycles and investigate whether the environment there has been favorable for microbial life.

MESSENGER: Mission to MercuryAfter a journey of more than 2 billion miles and three and a half years, NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft made its first flyby on Jan. 14.

NASA Top Exploration and Discovery Stories of 2007NASA moved forward in 2007 to explore the solar system, expand our knowledge of Earth and its place in the universe, and continue building the International Space Station. While the space shuttle flew three highly successful missions to continue the station’s assembly, construction began on a variety of projects designed to send astronauts to the moon to establish a permanent outpost, where they will prepare for eventual voyages to Mars. Space science missions were launched to Mars and the asteroid belt, while closer to home, Earth science satellites made a number of key discoveries, such as discovering how waterways beneath an Antarctic ice stream affect sea level and the world's largest ice sheet.
